For Scotts Valley polygonum, The species persists as three occurrences on three properties: Polo Ranch, Scotts Valley High School Ecological Reserve, and Salvation Army land. The occurrences are conserved on Scotts Vally High School Ecological Reserve and on Polo Ranch, but not on Salvation Army land. For Scotts Vally spineflower, the species persists as four occurrences on four properties: Polo Ranch, Scotts Valley High School land, Glenwood Open Space Preserve and Salvation Army land. The species is conserved on Polo Ranch and Glenwood Open Space Preserve, partially on Scotts Valley High School land, and not on Salvation Army land.

Scotts Valley polygonum: Two occurrences exist on three properties in a recently urbanized area at the northern edge of the city of Scotts Valley, with a geographic range of 0.03 square kilometers (7.4 acres). As of 2012 the species has declined to 128 plants on 61 square meters (73 square yards), having decreased from 604 plants in 2003, 1,612 plants in 1998, and 2,388 plants in 1997. In 2013 the primary threats to P. hickmanii are habitat alteration due to adjacent land uses and developments, and invasive plant species and accumulation of thatch. In 2015, five individuals were observed on the high school land. In 2016, zero individuals on high school land and Salvation Army land, and 12 individuals on Polo Ranch.

1. Polo Ranch: In 2009 the City of Scotts Valley approved a plan to construct 40 houses on 6 ha, along with establishing an open space preserve on 40 ha of which 14 ha of sensitive habitat would be fenced and under a conservation easement. The area under conservation easement is supposed to be managed by a conservation organization to benefit the listed plant species (P. hickmanii, C. robusta hartwegii, Plagiobothrys diffusus), including reducing invasive plants by grazing along with other adaptive management practices. As of 2016, little to no management has occurred. 2. Scotts Valley High School Preserve: In 2016, controlled horse grazing occurs on the high school preserve in an effort to benefit the listed plant species by reducing invasive grasses. 3. In 2016 the USFWS intends to discuss with the owner of the Salvation Army a plan to reduce invasive grasses.

Vegetation clearing commenced in summer of 2012. As of 2016, little to no management has occurred. 3. Salvation Army land: The USFWS intends to try to work with the Salvation Army in 2017 for restoration of the primary site.

Based on the results of studies, Ohlone tiger beetle expert, Dick Arnold, has drafted a management report titled: Review of Historical and Current Land Use Practices,Characterization of Suitable Habitat, and Habitat Management Recommendations for the Endangered Ohlone Tiger Beetle,Cicindela ohlone (Coleoptera: Cicindelidae). This is an unpublished report in draft form as of 8/5/11. In 2016, adaptive management is being used for Scotts Valley polygunum and Scotts Valley spineflower on the Scotts Valley High School Preserve. There is little to no management on the Polo Ranch, and no management on the Salavation Army land. USFWS intends to discuss management options with the owners of the Salvation Army land the Polo Ranch.
